Abstract
The invention discloses a minute pump assembly for a clutch. The minute pump assembly comprises a cylinder body; the side wall of the right end of the cylinder body is provided with an installation disk; the right end of the cylinder body is provided with an opening; a dust cover is covered on the opening; a piston is arranged in the opening of the right end in a sliding way; the right end of the piston is provided with a cavity; the side wall of the left end of the piston is provided with grooves; leather collars are embedded in the grooves; the left end of the cylinder body is provided with an oil absorption port; a stifle is covered on the oil absorption port; the side wall of the cylinder body is communicated with a bleed screw; and a bleed cap is screwed on the bleed screw. The minute pump assembly has a simple and compact structure, and a small volume and can effectively prevent dust and oil leakage.
Description
Technical field
The present invention relates to a kind of clutch slave cylinder assembly.
Background technique
What clutch used in the present automobile operation mechanism all is conventional clutch slave cylinder, and the piston in its structure only is provided with seal ring between inner walls, occur oil leakage phenomenon in the course of the work easily; In addition, in the linkage structure of existing piston and push rod; Behind the gap that the clutch plate wearing and tearing are produced, can not carry out replenishing automatically, the shortcoming of this system is complex structure; Wheel cylinder center and separator levers are difficult to guarantee concentricity; Produce noise and impact, make wheel cylinder produce eccentric wear easily, thereby influence the working life of wheel cylinder.
Summary of the invention
The present invention provides a kind of problem to leakage of oil in the above-mentioned clutch slave cylinder working procedure, provide simple in structure, compact, volume is little, can effectively prevent the clutch slave cylinder assembly of into grey and leakage of oil.
Technical solution problem of the present invention provides following scheme:
A kind of clutch slave cylinder assembly comprises cylinder body, has mounting disc on the right-hand member sidewall of said cylinder body; It is characterized in that: said cylinder body right-hand member has opening, is covered with dust-proof cover on the said opening, is slidingly fitted with piston in the said right-end openings; The right-hand member of said piston is provided with cavity, has groove on the said piston left end sidewall, is inlaid with apron in the said groove; The left end of said cylinder body is provided with inlet port, and said inlet port is stamped stifle.
Be linked with bleed screw on the sidewall of said cylinder body, be combined with the venting cap on the said bleed screw.
Working principle of the present invention: when the oil inlet hole oil-feed, the leather cup on the piston is further opened, pressure is high more; Sealing effect is good more, is provided with dust-proof cover in the termination of cylinder body, can effectively prevent dust; Make to produce pressure in the cylinder body active chamber, promote piston and push rod and outwards move, promote disengaging yoke through push rod again; Release bearing, separation platen; Thereby the effect that the power that reaches the cut-out motor transmits to speed changer, the spring in the described active chamber plays buffer function when pistons work, reduce noise and impact.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a lateral cross section structural representation of the present invention.
Embodiment
Referring to accompanying drawing, a kind of clutch slave cylinder assembly comprises cylinder body 1; Have mounting disc 2 on the right-hand member sidewall of said cylinder body 1, said cylinder body 1 right-hand member has opening 3, is covered with dust-proof cover 4 on the said opening 3; Be slidingly fitted with piston 5 in the said right-end openings 3, the right-hand member of said piston 5 is provided with cavity 6, has groove 7 on the said piston 5 left end sidewalls; Be inlaid with apron 8 in the said groove 7, the left end of said cylinder body 1 is provided with inlet port 9, and said inlet port 9 is stamped stifle 10; Be linked with bleed screw 11 on the sidewall of said cylinder body 1, be combined with venting cap 12 on the said bleed screw 11.
